7 Claims, 15 Drawing Figures MACHINE'FOR ASSEMBLING A CONNECTING DEVICETO AN ELECTRICAL DEVICE BACKGROUND OF THE INVENTION Electrical coils, ofthe type used in solenoids, motors, and other electrical devices, areusually wound on a bobbin having flanges at each end. It is commonpractice to mount electrical terminals in one of the bobbin flanges andconnect the tap wires from the coil to the terminals by a solderingoperation. When the external connections arelater made, the lead wiresare then soldered to the same terminals so that the lead wires will beconnected to the tap wires of the coil.

The instant inventionis directed to the achievement of an apparatus forterminating the tap wires from an electrical coil. Itis-a further objectto provide an apparatus for assembling electrical connecting devices toa coil bobbin and concommitantly forming electricalconnections betweenthe connecting I devices and the tap wires from the coil which is woundon the bobbin.

These and other objects of the invention are achieved in preferredembodiments thereof which are briefly described in the foregoingabstract, which are described in detail below, and which are shown inthe accompanying drawing in which:

FIG. I is a perspective view of a preferred form of apparatus inaccordance with the invention.

FIG. 2 is a perspective view of an electrical coil wound on a portion 20of each connecting device thus obviates the necessity of chemicallystripping the varnish type insulation from the tap wires.

In accordance with the instant embodiment, the connecting devices areprovided as right-hand strip I and left-hand strip 15', the two typeshaving their tab portions I8, 18' extending in opposite directions forreasons which will be apparent from an inspection of FIG. 2.

The general principles of the apparatus aspects of the instant inventionwill be apparent from a brief consideration of FIGS. 3-7 which show someof the essential structural features in the apparatus and illustrate themanner in which the connecting devicesare inserted into the bobbin andthe tap wires connected to the connecting devices. A bobbin 4 is firstpositioned on a bobbin holder 22 with the heavy flange section 12 facingconnecting device strips 15, 15'. The bobbin holder is moved towards thestrips and the strips are fed relatively towards the bobbin holder (FIG.5) until the leading connecting devices of the strips have been insertedinto the openings 36 in the flange. The tap wires 34, 34' are positionedin keyhole slots 26, 26' on the ends of arms 24, 24 which are pivoted ona common axis 25 beneath the bobbin holder 22. After the connectingdevices have been inserted into the flange portion 12, the arms 24, 24'are swung inwardly and 7 generally towards the connecting devices (FIG.6) until the bobbin having connecting devices thereon in accordance withthe invention.

FIGS. 13 and 14 are views similar to FIG. 11 but showing it atsuccessive stages of the operating cycle.

FIG. 15 is a view taken along lines 15-15 ofFIG. 10.

Referring first to FIG. 2, an electrical coil 2 in accordance with theinvention comprises a winding of relatively fine wire on a bobbin 4having spool portion 6 which supports the winding and flanges 8, 10extending from the ends of the spool. The flange 10 has a relativelythick cross section on one side thereof as shown at 12 which is providedwith openings 36 in which connecting devices 14 are received.

The connecting devices are advantageously manufactured in the form of acontinuous strip 15, each device comprising a mounting arm 16 havingserrated edges, a terminal portion in the form of a laterally extendingtab 18, and a ferrule-forming portion 20 which is in axial alignmentwith the mounting arm 16. This ferrule-forming portion is adapted to becrimped onto one of the tap wires 34, 34' of the winding end and may beprovided with insulation piercing grooves in accordance with US. Pat.Nos. 2,800,638 and 3,1 1 1,554. The conductors commonly used for coilsare usually provided with a thin film of varnish-type insulation such aspolyvinyl formal resin which is commercially available under thetrademark Formvar. The

provision of insulation piercing means in the ferrule-forming tap wiresare disposed above the ferrule-forming portions of the connectingdevices. These ferrule-forming portions 20, 20 are supported on anvils28, 28 so that as a die-plate 32 moves downwardly towards the anvils,the forming surfaces 30, 30' of the die plate will crimp theferrule-forming portions of connecting devices onto the wires. Aftercompletion of the crimping operation, the connecting devices will extendoutwardly in the plane defined by the flange section 12 and it isdesirable to bend the connecting devices inwardly so that their tapportions 18, 18' are disposed in spaced relationship to the surface ofthe coil as shown in FIG. 2. This may be done by hand or by a suitablebending jig. When external connections are to be made to the coil, it ismerely necessary to engage complementary receptacle type terminals withthe tabs I8, 18'.

A complete apparatus in accordance with the invention (FIG. 1) comprisesa connecting device inserting means 40, and a bobbin jig 42 which aremounted on a common baseplate 44 which in turn is mounted on the platen46 of a suitable press 48. The press may be of any desired type, forexample, as shown in US. Pat. No. 3,046,636. The inserter 40 and the jig42 are located beneath, and on opposite sides of, the press ram 50 towhich the previously identified die-plate 32 is secured as shown.

The inserter 40 in the disclosed embodiment is of the type fullydescribed in application ser. No. 6,103 filed Jan. 27, 1970, so thatonly a brief description of its operation is required for purposes ofthe instant disclosure. Inserters of this type comprise a horizontallyreciprocable slide member 52 (FIG. 9) having a feed track plate 53secured to its upper surface in which are provided tracks for feedingthe strips I5, 15' of connecting devices. The slide 52 is mounted onstationary frame means generally indicated at 54 which is supported onthe common baseplate 44. Reciprocation of the slide is effected by apiston cylinder 56 mounted beneath the frame portion 54 and a verticallyreciprocable faceplate 58 is mounted on the front of the apparatus whichincorporates shearing means to shear the leading connecting devices 14,14' from the strips. Subsequent to shearing of these connecting devices,they are gripped by spring-biased gripping fingers 62 mounted on amounting block 60 on the top of the plate 58 and held as shown in FIG. 9while the slide moves towards the bobbin jig to insert the mountingportions 16, 16' of the connecting devices into the flange 12 of thebobbin mounted on the holder portion 22 of the jig.

The piston rod of the piston cylinder 56 is connected to a laterallyextending block 66 which in turn has a pivotal connection to aconnecting rod which extends towards the jig 42.

This connecting rod actuates the jig in a manner which will be describedbelow to bring about the movement of the arms 24, 24' and the movementof the holder 22 relatively towards and away from the inserter duringthe operating cycle.

The bobbin jig 42 comprises fixed frame blocks 70, 74 which are mountedin spaced-apart relationship on the upper surface of plate 44 and whichare separated by spacer blocks 73, 74 to which they are secured,Recesses 76, 78 (FIG. 11) are provided on the opposed sides of theblocks 70, 74 at the upper ends thereof for the accommodation of areciprocable main slide 80, retainer plates 81, 81 being mounted on theupper surfaces of the fixed blocks and extending over edge portions ofthe slide to retain the slide as shown in FIG. 11. The previouslyidentified anvils 28, 28' extend from an anvil plate 82 which is securedby fasteners 83 in a suitable recess in a faceplate 84 which is, inturn, secured by fasteners to the ends of the fixed blocks 70, 74.

Main slide 80 is reciprocated by a toggle mechanism comprising links 88,90, the link 88 being pivotally mounted at the left-hand end of theslide in a recess 92 on the underside of the slide. The link 90 has apivotal mounting 96 on the previously identified spacer block 73 and thetwo links have interfitting ends which are pivoted on a common pivot pin98. It will thus be apparent that when this toggle is broken as shown inFIG. the main slide will be in its retracted position and when thetoggle is straightened, the slide will be moved to its forward position(FIG. 9).

The actuation for this toggle mechanism is provided by a lever 100 (FIG.10) which is pivoted at its left-hand end 102 in a suitable recess infaceplate 84. Roller means 104 on the end of this lever are received inslots 106 provided in depending ears 108 on the link 90. Lever 100 isoscillated by means of a cam follower 110 on the end of a stub shaft 112having a reduced end 114 which is mounted in the lever 100 intermediateits ends. Cam follower 110 is received in a confined cam track 116 of acam block 118 which is slidably supported in a guide track 120 in block74, retainer plates 122, 124 being secured to the block and overlappingthe camming block 118 as shown in FIG. 11. A connecting block 126,secured to the cam block 118 and extending laterally therefrom, has apivotal connection 128 to the end of the previously identifiedconnecting rod 68.

It will be apparent from a comparison of FIGS. 9 and 10 that when thecam block 118 moves rightwardly from the position of FIG. 10, by theconnecting rod 68, the toggle mechanism 88, 90 will be straightened andthe main slide will be moved leftwardly; during reverse or leftwardmovement of the cam block, the toggle is broken and the main slide 80 isretracted.

The previously identified bobbin holder or spindle 22 is mounted on thehorizontally extending arm portion 130 of an L-shaped bracket, thevertically extending arm 131 of which is secured by a fastener 134 to avertically extending ear 132 on a secondary slide member 136. In orderto firmly position the bobbin on the holder 22, it is desirable toprovide a slot 19 in the bobbin and to mount a biasing plate 21 in thisslot. It will be understood that this plate is outwardly biased by aspring and that when the bobbin is moved down onto the bobbin holder(FIG. 4), the plate will be resiliently moved into the slot. The plate,however, urges the bobbin rightwardly as viewed in FIG. 4 with respectto the bobbin holder so that the left-hand end of the bobbin, the sideadjacent to the crimping die plate, will be accurately and preciselylocated.

As shown best in FIG. 11, a channel 138 is provided on the upper surfaceof a primary slide 80 for the accommodation of this secondary slide andsuitable retainer plates or guide plates are secured to the main slideand extend over the surface of the secondary slide. Secondary slide 136is biased leftwardly with respect to primary slide 80 by means of aspring 140 contained in a recess 142 which extends inwardly from therighthand end of the secondary slide. A plate 144 is secured to theprimary slide and extends across this recess to retain the spring inposition. It should be mentioned at this point that spring 140 willordinarily bias the secondary slide leftwardly until the L-shapedbracket 131 moves against a mounting block 154, described below, whichis secured to the left-hand end of the primary slide. When the primaryslide moves leftwardly to the limit of its travel, FIG. 9, a stop screw148, mounted in an ear extending upwardly from the secondary slide,moves against a transversely extending stop bar 146 so that the primaryslide moves slightly beyond the secondary slide and a gap 149 is leftbetween the block 154 and bracket 130. The stop bar 146 extendstransversely over the upper surface of the secondary slide and has itsends secured to mounting blocks 152, 152 which are secured to thepreviously identified retaining plates 81, 81' and the fixed frameblocks, 70, 74 as best shown in FIG. 11. When the parts are in theposition of FIG. 9 it should be noted that the transversely extendingretainer bar 144 is against the right-hand end of the secondary slide.When the primary slide is in its retracted position (FIG. 10) a slightgap 151 will exist between the surface of bar 144 and the right-hand endof the secondary slide. The function of the secondary slide, and thesignificance of its limited movement of the primary slide are describedbelow in the description of the operation.

The wire-positioning anns 24, 24' are pivotally mounted on a commonpivot pin 25 contained in the block 154 which is secured to the mainslide so that this block will move with the slide as is apparent fromFIGS. 9 and 10. These arms have inner portions 23, 23 which are disposedbeneath the bobbin holder 22 and have vertically extending transitionsections 27, 27' intermediate their ends. The end portions 29, 29 of thearms are directed inwardly, as best shown in FIG. 3, and thewire-receiving slots 26, 26' are provided in vertically extending earson the ends of the arms. The arms are shaped such that the slots 26, 26will be disposed adjacent to the forming surfaces 30, 30 of thedie-plate 32 when the arms are swung inwardly as illustrated in FIGS.4-7. Arms 24, 24 are biased by springs 155, 155' in opposite directionsto their outer positions (FIGS. 3 and 12). These springs have theirinner ends secured to pins on the intermediate portions 23, 23' of thearms and have their other ends anchored to pins extending upwardly fromthe retainer plates 137, 137' and the primary slide 80.

The arms are swung inwardly from the positions of FIGS. 4 and 12 tothepositions of FIGS. 7 and 14 during rearward movement of the primaryslide by latch arms 156, I56 disposed on each side of the centralsection of the primary slide and in recesses 157 and the undersides ofthe blocks I52, 152'. Latch arms 156, 156' are pivoted on pins 158, 158at the rearward ends of the blocks 152, 152' and are biased inwardlytowards the primary slide by springs 159, 159' which are contained inholes in the blocks 152, 152' and which bear against the outwardlyfacing edges of the arms.

The opposed inner edges of the latch arms 156, 156 have inwardlydirected intermediate portions 160, 160' which are engaged by dependingpins 170, in the wire-positioning arms. The inclined edge portions 160,160' of the latch arms extend to forwardly facing shoulders 162, 162'which are adapted to receive the pins 170, 170' during forward movementof the main slide as will be described below. Forwardly of the shoulders160, 162, the arms again have opposed convergent edges 164, 164 and theends of the arms are provided with upstanding ears 166, 166'. As will beapparent from FIG. 8, these ears are so located that they are engaged bythe comer portions 168, 168' of the die-plate 32 when the ram movesdownwardly to its lowermost position.

The operation of the disclosed embodiment is as follows: the operatorfirst positions a bobbin on the bobbin holder 22 of the bobbin jig asillustrated in FIGS. 3 and 4. He then actuates the apparatus by asuitable foot switch or other convenient switch to supply compressed airto the piston cylinder 54 and initiate the cycle. Initially, theinsertion slide of the inserter 40 and the connecting rod 68 are movedrightwardly. During such rightward movement of the insertion slide 52,the leading connecting devices of the two strips of connecting devicesare severed from the strips and carried to the position shown in FIG. 9.Concommitantly, the rightward movement of connecting rod 68 causes thecam 118 to be moved to the right-hand end of the bobbin jig. This causesthe toggle mechanism 90, 88 to be straightened with accompanyingleftward movement of the main slide 80 of the bobbin jig so that thebobbin is moved relatively towards the inserter. During this portion ofthe cycle, that is while the inserter slide is moving rightwardly andthe main slide 80 is moving leftwardly, the connecting devices areinserted into the openings in the flange portion 12 of the bobbin.

The instant of insertion is shown in FIG. 9 and as pointed out above,when the parts are in the positions of this Figure, the stop screw 1148of the secondary slide is against the stop bar 146 and the retainerplate 144 is against the right-hand end of the secondary slide. Thesecondary slide is thus firmly held against any movement and the bobbinitself will thus be supported against right-hand movement so that itwill not yield or retreat during the forcible insertion of the mountingportions l6, 116' of the connecting devices into the flange portion 12of the bobbin.

During this first portion of the operating cycle, the pins 170' movealong the convergent edges 160, 160' of the latch arms and bias thelatch arms outwardly and at the conclusion of this portion of the cycle,the pins 170, 170' are lodged in front of the shoulders 162, 162' of thelatch anns. The positioning arms remain in their swung out positions(FIG. 5) but are swung inwardly during subsequent retracting of the mainslide as described below.

During the second portion of the operating cycle, the connecting rod 68returns to its original position, that is, it moves leftwardly as viewedin FIG. I; and the toggle 88, 90 is broken and the main slide 80 of thebobbin jig is moved rightwardly to the position of FIG. 10. During thisrightward movement of the main slide, the pins 170, 170' are preventedfrom moving rightwardly by the shoulders 162, 162' so that thewire-positioning arms are caused to pivot about their pivotal axis asthis axis moves rightwardly and their ends are swung inwardly to thepositions of FIGS. 7 and 14. The inward swinging movement of these armsoccurs during the rightward movement of the bobbin mounted on the bobbinholder 22 so that at the conclusion of the portion of the cycle theferrule-forming portions of the connecting devices are supported on theupper surfaces of the anvils 28, 28' and the wires are located directlyabout these ferrule-forming portions. It should also be noted that atthis stage of the operating cycle, the secondary slide 136 is at thelimit of its limited leftward movement under the influence of the spring140 and is against the side of the block 154.

The press 48 is then actuated to drive the ram 50 and the die-plate 32downwardly to crimp the ferrule-forming portions of the terminals ontothe tap wires. It is inevitable in a crimping operation of this type,that some extrusion of the metal will take place resulting in anelongation of the ferrule-forming portion. This elongation isaccommodated by the clearance 15] between the right-hand end of thesecondary slide 136 and the retainer plate 144 on the primary slide. Inother words, the secondary slide will move rightwardly as viewed in FIG.10 by a very slight amount when the ferrule are crimped onto the wiresto accommodate the elongation of the ferrules which results from thecrimping process.

When the die plate is lowered to the position of FIG. 7, the corners168, 168 of the die plate engage the ears 166, 166' on the ends of thelatch arms and bias these ears outwardly until they move past the pins170, 170'. The springs 155, 155 then cause the wire-positioning arms 24,24 to be swung outwardly to the positions of FIG. 3. Upon ascent of theram, the parts are returned to their original positions and the operatorcan remove the bobbin from the bobbin holder.

A terminated bobbin in accordance with the instant invention has theadvantage of providing an integral terminal on the connecting devices towhich its tap wires are connected so that when it is assembled to afurther apparatus, the necessary connections to the coil on the bobbincan be made by merely engaging terminals on the apparatus with theterminal portions l8, 118' on the bobbin. Furthennore, the connectingdevices in the bobbin and the electrical connection between theseconnecting devices and the tap wires are conveniently located in spacedrelationship to the surface of the windings and between the bobbinflanges. This arrangement provides a maximum amount of protection forthe connecting devices in the event that they should be carelesslyhandled or dropped.

The method and apparatus of the instant invention offer substantialadvantages in that at least one, and possibly two soldering operationsare avoided and are combined with what was previously a simple terminalinserting operation. The cycling time for the apparatus disclosed is notsubstantially greater than the cycling time for previously knownmachines for inserting terminals into bobbins. However, the previouspractice in the art accomplished only the insertion or assembly of theterminals to the bobbins and the soldered electrical connections had tobe made at a later time and in a separate manufacturing step. Inaccordance with the instant invention, the entire terminating andassembly operation is carried out in a single step.

Changes in construction will occur to those skilled in the art andvarious apparently different modifications and embodiments may be madewithout departing from the scope of the invention. The matter set forthin the foregoing description and accompanying drawings is offered by wayof illustration only.
